Allow debug and trace log statements to be printed in log files

System logs file appenders were created with an info threshold which
was preventing debug and trace log statement to be printed in the
files. File appenders should not have a threshold. Instead, the root
logger should have a proper level (i.e. info) so if a specific logger is
using a finer grain level (e.g. debug, trace), the log statements won't
be filtered out by the appender.

Set the root category to info and no longer set the file appender
threshold when creating system logs.
